Does anyone know how SOC or range is calculated on the Roadster? My fake sheet (bricks 46-54) has confused the roadster to drop it's range to 17 miles.

17 miles in standard or range; ideal or rated? Standard could make sense. Range has to be calculated from the brick with the lowest amount of left energy. This is what I believe: SOC range in standard mode: 10 - 100 % SOC (not sure about the 10%) SOC range in range mode: 0 - 110 % SOC Your lowest brick has a SOC of 22% which is 12 % in standard mode. That would be 141 miles (rated?) for 100 % SOC. - - - Updated - - - That's strange. Brick #47 has a higher voltage but lower SOC... So the SOC seems not to be calculated from the voltage only.
Thanks Marco. It was in standard mode. Before the mileage drop, I said I had 144 mile range, I think I need to do more playing on the fake sheet and gather more data.
I noticed the lowest brick as I bring up the voltage on it, that range start to rise, seem like a direct correlation but I assume some SOC is factored in it. Sigh, I accidentally burnt out resistor R73 on the dc-dc converter... hopefully this will be an easy fix. Edit: BMB fixed, in case anyone cares, R73 is likely a current limiting resistor to the DC-DC converter, so if the DC-DC converter ever goes bad R73 will burn out.
